It focuses on the theory of the mineral functional materials " improving the anti - chloride permeability and the chloride binding . the main achievements of this article include : 1 ) use the technology of xrd , sem , bet , laser particle size distributor etc to test the component , the construction , particle size distributor , specific surface etc of micro - silica , ultra - fined slag , high quality fly ash , meta - kaolin clay , four types of the mineral functional material , theoretically analysis the functions which the four mineral functional minerals act on cement concrete , namely pozzolanicity effect , filling effect , micro - aggregate effect , surface adsorption effect and so bring into play the affect of plastification , lowing of temperature , reinforcement , improvement of durability . base on this analysis we can conclude that the proper diameter of the mineral functional material is 5 m - 15 m , that is blain fineness 4500cm2 / g - 7500cm2 / g 本论文的主要成果包括以下几个方面: ( 1 )采用xrd 、 sem 、 bet 、激光粒度分析仪等多种测试手段,探明了以硅灰,超细磨粒化高炉矿渣,优质粉煤灰及偏高岭土超细粉等4种超细矿物功能材料的组成、结构、粒度分布、比表面积等基本性质;从理论上分析了矿物功能材料在混凝土中的4种效应,即火山灰效应、填充密实效应、微集料效应、表面吸附效应,并由此发挥出增塑、温峰削减(降热) ,增强及耐久性改善等作用;通过相关理论分析,推导出矿物功能材料的合理粒径范围在5 m 15 m ,即勃氏比表面积为4500cm ~ 2 g 7500cm ~ 2 g 。
Because a conventional quantum well is needed to add in the novel structure , many experiments were made on conventional gaas / algaas qwips . the experiment results based on various test methods were well analyzed . the detectivity of conventional gaas / algaas qwips can be comparable to the current level gradually 由于改进结构中需要加入一常规量子阱,因此针对常规结构做了部分实验,由多种测试方法得到大量实验数据,并对其进行了全面的分析,常规gaas algaas量子阱红外探测器的研制已经逐步趋向正常化。
The structure evolution and reaction mechanism of silicon - iron composite powders treated at the temperature ranging from 700 c to 1200 c respectively were carefully investigated through xrd , sem , epma , dsc . it was found that the chemical formula , fe + si - fe ( si ) + fe3si ( si ) , controls the reaction process , and the reaction mechanism of powder homogenization was clarified 通过利用xrd , sem , epma , dsc等多种测试手段,详细研究了铁硅复合粉末带材在700 1200的热处理温度条件下的反应状况及结构变化,明确了反应过程中的化学方程式: fe + si fe ( si ) + fe _ 3si ( si ) ,并解释了各个热处理温度范围内,铁硅粉末均一化的反应机理。
